IMPROVEMENT IN CURTAIN-FIXTURES.

l'he Schedule referi*e@ 310 in these Letters Patent and makixig part ofthe same.

T0 all persons t0 whom these presents shall 00m0 Be it known thatI,BENJMIN MOSER OfWEI- tha.m, Middlesex county, Starte of Massachusetts,

' ha.v e inv ented new and useful Improvements in Curtain-Fixtures; andtha.t the follow ing deseriptio'n, taken in connection wi-th theaccornpzmying drztwing,

- is a full and complete specification of tha Same.

'lhis inveution consists of a peculizrrly-arranged and cmistructedspring arm hzwing loose roller to bezrr upon the operating-qord aroundthe pulley of c-urtain- The qbject of this spring arm is t0 1nsurebeyonda possibility of doubt .the working f the Operating-cord, itspressure on the cord, nipping it while not absolutely binding 1it 1:0the roller, and insuring the 1equisite fric tion to produce the turningof the curtaiu-roller, and

.consequen'tly the winding 01 unwinding of' the eurtain,

as the ca-se may be, and also the balance of-the shade. In tlieaccompanying' draWing my improvements in curtain-fixtures areillustrated A in the drmvingrepresents a w indow-frame, and

B a rolle! arrauged to turix-in brackets O, 0ne ab euch si de of thewindow-frzrme, this toller being an ordinary curtain-roller.

D, argrooved pulley or wheel applied 130 one end of curtaii1-rqller,und.

E an endless cord passing pzr'rtzia.lly around-the saxne,for.turning theroller tcs-wind u'p o1 umfin'd the curt-ain thereto, this endless cordpassing arounda pulley, F, at lower portion of window-frame.

The arrangement and eonstruction 0f the several parts abovedescribed'are substantially the:same zus in ordinary curtain-fixturesofthe same dass.

G, an arm, which, a.t ea.qh end, is bent at right an gles to th ecentral portion, und by 0ne df its b'eut ends inserted within a,suitztble soeket of the roller bracket, at the end where the cord-pulleyot' ourtiainrolle: is loeated by the other projeeted over the plane ofthe rollr-pulley, 2u1d there provided with a fric tion-wheel, H, tobe2tr within the groove 0f the curt-ainpulley and upon the cord passiugtherein around it.

I, a coiled spring about the bent portion of arm G, by whieh it isfastened to the bracket.

One end of t-he spring I is interlocked with a notch, a, of thebracket', und ehe otl1er end twisted around the' central 01 mainpo1"tion 0f the arm G, as plainly s hown in the drawing.

By this application of a coiled spring tue attackment of the arm G tot-he brzwket0 is secured, und also an elastieity und. spring 130 Ehearm, prozluc'rng, consequently, an elastio und spring pressure byitsfxicti0mmlle1-carrying end upon the curtain-cord 011 the roller-pulley;By this pressure of the arm G upon the cmtain-cord the operation of theroller fr0m the pulling of the cord.to wind0r unwiud the curtain issecured beyond a doubt, and a complete bzrlzmeing 0f the curtainobtained, dispnsing entirely with the necessity 0f a st rong tensio n on'tl1e curtztin-cord am]. the use of a weighted tzmssel, should tasse1sbe ernployed in lieu 0f an endless cord.

By means of the friction-wheel 0f tue arm br ai1 easier and rezrdiermovement of the cord around the curtain-roller is obt-ztined.

' Ha'ving-thus described my improvemeuts in eurtninfixtures,

I shzrll state my olaim as t'ollows:
